This invention relates to sliders for separable fastener stringers. Moreparticularly, the invention relates to sliders employed on stringershaving double acting scoops facilitating movement of the sliders in bothdirections on the stringers, and to the provision of means for couplingadjacent wide end portions of two sliders on a pair of stringers, and tocover the stringer opening. intermediate the coupled sliders. The novelfeairom the following description when taken together withtheaccompanying drawing, in which joined at the wide end in a connectingweb 24 certain embodiments of the invention are disclosed, and'in whichthe separate parts are designated by suitable reference characters ineach of the views; and in which:

Fig. 1 is a plan view of two sliders arranged on a pair of stringersincoripled relationship, with part of the construction broken-away.

Fig. 2 is a section on the line-2--2 of Fig. 1 omitting the stringers. 1

Fig. 3 is a view similar to Fig. 2 showing only a part of theconstruction and showing a modification, and 1 s Fig. 4 is a viewsimilar to Fig. 2 showing .only a part of the construction andshowinganother modification.

In Fig. 1 of the drawing, I have shown at l and l I a portion of twostringers, to the beaded edges of which are attached links or scoops ofthe double acting type,that is to say, links or scoops which can becoupled and uncoupled by sliders moving in both directions on thestringers, I for example, by the sliders l3 and I4 which have theirnarrow ends I5 and 16 respectively arranged in opposite directions, thewideends l1 and ll of the sliders being arranged adjacentwhen thesliders are brought together, I

In some instances or uses of the invention, it may be desirable to joinor couple the sliders at a particular position along the stringers. Insuch cases, a stop I9 will be arranged on one stringer, for example, thestringer H) in the construction shown. This stop will definitel locatethe position at which the sliders l3 and H are to be coupled together.

In the construction shown in Figs. 1 and 2, the slider I3 has at itswide end H a projecting shield plate 20 including an outwardlyprojecting slightly headed pin 2|, which in the construction shown isintegral with the plate 20. On the Wide end I8 of the slider I4 isacorresponding projecthole aperture23 facilitating coupling anduncoupling of the headed pin 2| with the plate 22.

The plates 20 and 22 extend from thewidest portiqn of the sliders l3 andH as will clearly appear from a consideration of Fig. 1 of the drawing.Thus, these plates serve to cover and shield the opening formed betweenthe spaced stringers intermediate the wide ends l1 and I8 of thesliders.

The sliders l3 and I4 may be of any desired construction and eachcomprise channeled bodies and, as seen in Figs. 1 and 2, the slidershave on one side wall elongated loops 25; with which are coupled fingerrings or pulls 26.

In Fig. 3 of the drawing is shown a slight modification, particularlyin'the structure of the .pin

2|. Substituted for this pin is a longer pin 21 having an aperture 28 inits outer end portion sufficiently large to receive a padlock 29. Asidefrom this structuraldifierence, the structure of Fig. 3 may be the sameas that shown in Figs. 1 and 2 or the structure of Fig. 4 which is laterdescribed. The use of a lock in coupled sliders will be practical inmany adaptations and uses of the invention, particularly when applied toluggage or enclosures for any type or kind, or a compartment and mightevenb used on tent structures.

The structures illustrated in Fig. 4 of the drawing shows an adaptation"of the coupled sliders to fasteners employed on tents or similarenclosures which should be accessible internally and externally of theenclosure. With this construe? tion, adjacent wide ends of sliders 30,31 are provided with two shield plates instead of, one, the slider 30having a plate 32 with a pin 33 thereon and another plate 34 at theopposite sideportion of theslider. The slider 3| has a plate 35 with akeyhole aperture 36 therein and at the other side thereof a plate 31.The additional plates 34- and 31 simply form closures for the opening atthe other side of the stringers, The slider 3| or the side walls thereofare provided'with pull supporting loops similar to the loops 25'andthese loops are partially indicated at'38.

It will be understood that the particular type of coupling employedbetween the adjacent ends of the sliders may be varied to suit differentinstallations and uses. When the stop [9 is removed .from the stringerth sliders, when coupled together, are collectively movable along thestringers. M

It will be apparent that the projecting flanges ing shield plate 22having centrally thereof a keyor plates onthe sliders are disposedoutwardly of the channeled area of the sliders to freely pass over thestringer links or scoops in the movement of the sliders along thestringers to couple and uncouple the same.
